CONTROL DEVICE FOR SHEET-SEPARATORS.

Specification of Letters Patent.

Patented Apr. 7, 1914.

To all whom it may concern: '1

Be it known that I, J Aoon HEINRICH, subject of Germany, residing at Nuremberg,

Bavaria, Germany, have invented certain.

suction devices periodically served by a:

pump are employed, one of said conveyers lifting the separating layers off the pack to be disassembled with a rising movement, and the other conveyer with a lateral movement lifting off the sheets of metal foil. For this purpose there is arranged in the suction conduit between the pump actuating the suc-.

tion device and the latter itself a distribution device which serves to suddenly throw the suction device into and out of operation.

Two embodiments of the invention are shown in the accompanying drawings, in which I "Figure 1 is a schematic view, illustrative of the improved distribution device connected to a constantly operating pump, the latter appearing in section. Fig. 2 is a sec tional side view, and Fig. 3 a plan view, while Fig. 4 is a section of a modified form of distribution device. I

In both'forms of construction the distribution device is provided with a cook. or valve housing 70, which is connected to the air pump Z by an air delivery pipe m, and to the suction devices'by one, two or more feed pipes at 0, alternately fed by the pump and" corresponding in number with the number of said suction devices with which the machine is provided for disassembling the stacks. This alternate connection to the ,common suction pipe is known.

The invention consists in those parts which effect the precise movement of the valves.

In order to alternately feed the pipes n 0 from the constantly operating pump Z, two relatively displaced cams q 9 are mounted on a constantly rotating shaft p, and bearing on said cams at both sides are two pivoted levers 1 1- and s 8 each pair being connected by a spring 00. These levers either operate two slide valves t t (Figs. 2 and 3) or two puppet valves a, a (Fig. 4), one of said valves controlling the pipe n and the other the pipe of The control of the slide valves t, t and the valves '16,. is effected by the levers 1", 1' 8, 8 of each pair of levers which act against shoulders on bars w, 40 which latter are pivoted to the slide valves t, 25 (Figs. 2 and 3) and fixed to, or arranged to carry, the puppet valves u, M (Fig. 4). The arrangement of both pairs of levers is preferably such that one lever drops oif the cam surface after the other lever has risen onto the crest of the cam surface, the levers operating their valves when they leave the cam surface. rangement insures a sudden opening and closing of the valves and consequently a reliable action of the suction devices.

What I claim as my invention and desire to secure by Letters Patent of the United States is 1. An air distributing valve, embodying a casing having ports connected with suction devices, a constantly rotating shaft traversing said casing, a cam set on said shaft, a pair of pivotally mounted, flexibly This arsite sides of said shaft, and v lves within said casing actuated by said 1e ers to control the supply of air to said ports.

2, An air distributing valve, embodying acasing having ports connected with suction devices, a constantly rotating shaft traversing said casing, a cam set on said shaft, a'pair of levers pivoted within the casing at opposite sides of the shaft, a spring In testimony whereof I hereunto affix my coiligectinigl said levers and foil nogmally signature in the presence of two Witnesses.

ho ing t e same in contact wit sai cam, valves for controlling the supply of air to: JACOB HEINRICH 5 the ports, bars connected to said valves, and Witnesses:

means on said levers acting against said OSCAR BOOK, bars to operate said valves. HANS HEYBE.
